J2ME and files

[bartosz666]

after I launch netbeans' mobile phone emulator and choose the middlet to execute in the emulator screen I got a question if I wish to execute a 'reading' operation on file. When I click 'Yes' the program instead of reading the file - immidiately ends working and comes back to midlet list... and the requested read of file and printing its conent doesn work...

below is the code:

I just had a quick read of your code and I do not see an instantiation of a TextBox object. So I guess the problem is that your TextBox object is null being returned from get_helloForm() method. In fact you are returning the global object helloTextBox which has not been instantiated. I think you should look to see if you are getting a nullPointerException.

Somewhere in your code you need:
helloTextBox = new TextBox(String title, String contents, int size, int type);

In your initialise() method you are:
getDisplay().setCurrent(get_helloForm());

I think that a null is being returned from get_helloForm() so a nullPointerException will be thrown when you try to setDisplay() in your initialize() method.
